In his letter to Queen Elizabeth,
CuChullaine O’Reilly explained why he had presented Britain’s monarch with
the Encyclopaedia of Equestrian Exploration.

"While I am grateful to Prince Charles for expanding the scope of the
Encyclopaedia he was not the role model who inspired me. This image (right)
has hung in my office during the long years in which I sought to write the
Encyclopaedia. It has been a constant reminder that principles, not profits,
are the most important thing in life, that duty and devotion to others takes
precedence. I am confident that you have received many noble gifts
throughout your reign. Yet these three volumes represent the ‘crown jewels’
of my life’s work, thus I am presenting the first set of the Encyclopaedia
to you, the Queen of horse-humans."

Letter sent from Buckingham Palace in
response to the author.

“Her Majesty was touched to learn of the influence both The Queen and The
Prince of Wales have had in inspiring its creation.”
